Radiated EmissionsThe unintentional release of electromagnetic energy from an electronic device or apparatus.
Radiated ImmunityAbility to withstand electromagnetic energy that arrives via free-space propagation.
Radiated SusceptibilityThe determination or measurement of a device's capability to function in the presence of undesirable radiated EMI from external electromagnetic sources.
Radio Equipment DirectiveThe Radio Equipment Directive (RED) (2014/53/EU) ensures a Single Market for radio equipment by setting essential requirements for safety and health, electromagnetic compatibility, and the efficient use of the radio spectrum. It applies to all products using the radio frequency spectrum and(...)

Radio FrequencyRate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.
RFRate of oscillation in the range of about 3 kHz to 300 GHz, which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.
Radio Frequency CompatibilityAbility of antenna-connected RF receiver and transmitter subsystems operating within a system to function properly without performance degradation caused by antenna-to-antenna coupling.
Radio Frequency InterferenceAlso known as Electromagnetic Interference. A disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
RFIAlso known as Electromagnetic Interference. A disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.

Reality EngineeringThis column is comprised of a “lessons-learned” editorial approach and contributed by readers anxious to share their trials and tribulations in compliance engineering.
ReceiverAn electronic device that converts a signal from a modulated radio wave into usable information.
Receiver Equalizationa method of restoring a signal’s high-frequency components that the media preferentially attenuates
RectifierAn electrical device that converts an alternating current into a direct one by allowing a current to flow through it in one direction only.
Reliability EngineeringAn area of study focused on optimizing the reliability, or probability of successful functioning, of systems, such as airplanes, linear accelerators, and any other product.
ResistanceProperty of a conductor due to which it opposes the flow of current through it.
